Hi GMATClubber!

Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:

Statement 1: y lies between x and z. BE CAREFUL, we cannot conclude that x < y < z, because it could also be the case that z < y < xIn both cases, y lies between x and z on the number line. These two possible scenarios yield different answers to the REPHRASED target question. Case a: if x < y < z, then we can see that x < y.Case b: if z < y < x, then we can see that y < x.Since we cannot answer the REPHRASED target question with certainty, statement 1 is NOT SUFFICIENT

Statement 2: z < x < 0There's no information about y. So, there's no way to determine whether or not y < xSince we cannot answer the REPHRASED target question with certainty, statement 2 is NOT SUFFICIENT

Statements 1 and 2 combinedStatement 1 tells us that EITHER x < y < z OR z < y < xStatement 2 tells us that z < x, which RULES OUT the possibility that x < y < zSo, it MUST be the case that z < y < x, which means y < xSo, the answer to the REPHRASED target question is "YES. It is definitely the case that y < x"Since we can answer the REPHRASED target question with certainty, the combined statements are SUFFICIENT

Answer: C

Statement 1: y lies between x and z.But y may be greater than or smaller than xNOT SUFFICIENT

Statement 2: z < x < 0No mention of y henceNOT SUFFICIENT

Combining the two statementsz < x < 0 andy lies between x and zi.e. y must be smaller than x henceSUFFICIENT

Answer: option C

Hi Brent,

Nice solution! I do think you've made a mistake in the highlighted part though. I believe you meant to say:

Statement 2 tells us that z < x, which RULES OUT the possibility that x < y < zSo, it MUST be the case that z < y < x, which means y < xSo, the answer to the REPHRASED target question is "YES. It is DEFINITELY the case that y < x"
